Transcript of 1m and 2m Geography: Mapping Skills

It is the study of the earth's landscapes, peoples, places, and environments GEOGRAPHY To understand physical and human geography, we use maps. MAPS A map is an image that represents a particular area of the Earth's surface, usually from above and at a smaller size. Map Features To help us recognize and represent features, most maps use: Conventions = Land is often shown as green.
Seas, rivers and lakes are usually shown as blue.

Symbols = Identify natural and cultural features on topographic
maps. A map key or legend is used and is usually
placed in the bottom right hand corner. Do you think maps are useful? maps are a form of communication
visual communication is extremely helpful because geographers are interested in spatial relationships (this means place, distance, direction, size, shape)
gives us direction when we are in unknown areas Who are they useful for? Types of Maps Political Map Physical Map Topographic
Map Road Map Thematic Map
(Carte Tematiche) Reference Map
(Carte Geografiche) Maps that represent information on particular themes.

What theme does each map represent? Environmental
Map Includes the most important elements of a territory/region. What is the image below called? Compass Rose!

Why is it important? To indicate the direction in which the map is drawn to. Without the compass rose, you would not know which direction you are heading to.

4-point, 8-point, 16-point, 24-point, 32-point NORTH EAST SOUTH WEST Never Enter Stinky Washrooms If someone needed to go from Point A to Point B, without fixed reference points (N, E, S, W) it would be very difficult to describe the directions. The same is true of locations on the Earth's surface.

Geographers have solved this problem by creating a system of imaginary lines called lines of latitude and longitude. Latitude
Latitude lines are imaginary lines on the earth's surface that run horizontally. Degrees (°) latitude are numbered from 0° to 90° north and south. The Equator is the central line of latitude The Equator divides the world into two hemispheres: 1. Northern Hemisphere
2. Southern Hemisphere Longitude Longitude lines run vertically. They are also known as meridians.

Measures the distance from East to West. Zero degrees longitude is located at Greenwich, England (0°). The reference line of longitude is called the Prime Meridian The Prime Meridian divides the world into two hemispheres:
1. Eastern Hemisphere
2. Western Hemisphere Give the exact location (latitude and longitude) for each star.
Remember that for each set of coordinates, latitude is given first, then longitude. Homework (2m):

Read over class notes
Read page 22-23 in your textbook
"Where in the World Am I?" Activity Worksheet Homework:
Read page 26 in Book #1 The symbols and conventions make the maps clearer

With so many features on a map, there would not be enough space to write everything down in words.
